On radicals in differential invariants: global theory vs moving frames
Boris Kruglikov
The classical technique of moving frames allows to effectively compute differential invariants of group actions. A standard observation is that the expressions of differential inva…
Differential Invariants of Carrollian Spacetimes
Boris Kruglikov, Eivind Schneider, Wijnand Steneker
We compute invariants of Carrollian spacetimes, deriving them from the geometry of the screen bundle. For generic Carrollian structures we specify how to generate the entire algebr…
Scalar relative differential invariants
Boris Kruglikov, Eivind Schneider
Computation of polynomial relative invariants is a classical tool in algebra. Relative differential invariants are central for the equivalence problem of geometric structures. We a…
On CR manifolds of CR dimension 1
Boris Kruglikov
We classify all maximal symmetry models of CR dimension 1, depending on their Bloom-Graham and Tanaka types, give coordinate realization to some of those models and prove a general…
On globally invariant Euler--Lagrange equations for curves
Boris Kruglikov, Eivind Schneider, Wijnand Steneker
Invariant Lagrangians yield invariant Euler-Lagrange equations, and it was discussed in the literature how to compute those using various local methods. The focus of this paper is…
Geometric realizations of the Lie superalgebra D(2,1;a)
Anna Escofet, Boris Kruglikov, Dennis The
For every parabolic subgroup of a Lie supergroup , the homogeneous superspace carries a -invariant supergeometry. We address the question whether $\mathfrak{g}=\tex…
